Breast Asymmetry

Surgical correction — Paris 16e & Pontoise

A slight degree of breast asymmetry is entirely normal. When the difference exceeds one cup size, it may be classified as pathological and corrected surgically — with partial French social security reimbursement possible depending on medical criteria.

Types of breast asymmetry

Volume asymmetry

A notable size difference between the two breasts. Correction involves augmenting the smaller breast, reducing the larger, or both.

  • Breast augmentation of smaller side (implant or lipofilling)
  • Reduction of the larger breast if needed
  • Combined approach for optimal result
  • French SS coverage if > 1 cup size difference

Shape asymmetry

One breast may have a malformation (tuberous breast), asymmetric ptosis, different areola sizes, or a unilateral areolar hernia.

  • Correction of unilateral tuberous breast
  • Asymmetric ptosis lift
  • Areola harmonisation (periareolar)
  • Simultaneous treatment of both sides possible

Position asymmetry

The inframammary folds may sit at different heights, causing unequal breast positioning on the chest wall.

  • Lowering or raising the inframammary fold
  • Pocket correction (implant repositioning)
  • Sometimes combined with skin plasty
  • Technique adapted to each morphology

Procedure overview

  1. 01

    Consultation & classification

    Clinical assessment of the asymmetry, comparative measurements, full morphological analysis and discussion of goals.

  2. 02

    Pre-operative workup

    Standardised medical photography, compilation of the file for French social security prior authorisation if difference exceeds one cup size.

  3. 03

    Personalised surgical plan

    Defining the adapted technique: augmentation, reduction, ptosis lift, areolar correction or a combination.

  5. 05

    Post-operative follow-up

    Consultations at day 7, 1 month, 3 months and 6 months. Definitive result assessed at 6 months.

Frequently asked questions

Is breast asymmetry common?+
Yes — all women have some degree of breast asymmetry. A difference of less than one cup size is entirely normal and physiological. Only a more marked asymmetry is considered pathological and may warrant surgical correction.
From what difference is asymmetry considered pathological?+
The medical criterion recognised by the French Health Authority (HAS) is a volume difference of more than one cup size between the two breasts. Beyond this threshold, the asymmetry may be classified as pathological and may qualify for partial French social security reimbursement.
How is breast asymmetry corrected?+
The approach depends on each case: augmenting the smaller breast (with an implant or lipofilling), reducing the larger breast, or a combination of both. The surgical plan is tailored to the desired outcome and individual anatomy.
Can asymmetry and ptosis (sagging) be corrected at the same time?+
Yes. Dr. de Clermont-Tonnerre offers a combined approach allowing asymmetry and associated ptosis to be corrected in a single procedure, avoiding multiple anaesthetics and optimising the overall result.
Is breast asymmetry correction covered by French social security?+
Yes, under certain conditions. When the volume difference exceeds one cup size and is medically documented, partial coverage is possible after obtaining prior agreement (entente préalable) from the CPAM. Dr. de Clermont-Tonnerre assists patients in compiling this file.
Can asymmetry associated with tuberous breasts be corrected?+
Yes — breast asymmetry and tuberous breasts frequently coexist. Both can be treated simultaneously in a single procedure for optimal, harmonious results while minimising the need for multiple anaesthetics.
What scars should I expect?+
Scars depend on the technique used: in the inframammary fold for implants, periareolar for moderate reductions or areola corrections, vertical or inverted-T for more significant reductions. The least visible approach suited to your situation is always chosen.
How long is the recovery?+
Recovery ranges from 7 to 14 days depending on the extent of surgery. A sedentary activity can usually resume after 7 days, while intense physical activity is inadvisable for 4 to 6 weeks.
Will results be perfectly symmetrical?+
Perfect symmetry is the goal but not always anatomically achievable. A significant improvement is always obtained. A slight residual difference may remain due to individual anatomical characteristics — this is thoroughly discussed during pre-operative consultations.
What is the cost of breast asymmetry correction?+
Fees vary depending on the procedures performed, generally between €3,500 and €7,000. Partial social security coverage is possible when medical criteria are met. A detailed quote is provided at the pre-operative consultation.
